	Cracking survey has been a critical component for pavement management to identify pavement sections with condition problems, even though rutting, roughness and other types of pavement measurements are also used in the evaluations. The issue of cracking survey becomes even more important as it cannot be 100% automated at this time, and the protocol to calculate performance measures for cracks is not standardized yet. To effective use the results of cracking surveys with old analog tapes and newly collected digital images at AHTD, and also for future pavement design input with MEPDG, the proposed research would use the Automated Distress Analyzer (ADA) and MHIS Deluxe software to produce crack maps and related crack geometries from historical pavement images and new images. In addition, statistical analysis will be conducted in relation to variations of crack protocols. A protocol will be recommended based on future needs of using MEPDG at AHTD.
